After reading Theo's comments about no cookies. I really think the FO will let the infield situation play it's self out before we start to see these guys start to come up.
If Olt is playing well then someone will be released, traded, sent down to AAA. Which over all could change the time line of these prospects. With 2014 described as a "punt" year then well there is no hurry to bring up Bryant or Baez. That then could lead to Almora or Soler being one of the first to be called up.
I guess the same thing could be said about the outfield. If Lake, Sweeny and Schierholtz continue to progress positively then that will hold up Soler and Almora.
But if you are just looking for my opinion. Hell I don't know, but I am interested to watch and see how this will play out.
